Important safety instructions

Caution: Check the red power supply voltage switch setting before

installation. The setting should be the same as your local power voltage (115 V for North America. And 230 v for Europe and other countries). Change the voltage setting if necessary. Failure to take this precaution could result in damage to your equipment and could void your warranty.

Setting up the power supply

To install the new power supply:

1 Turn off your computer. 2 Unplug the power cord from your computer. 3 Open your computer case. For instructions, see your computer’s

user guide.

4 Disconnect power supply cables from the system board and

peripheral devices, such as hard drives, optical drives, and fans. Make sure that you note where all the power connectors are because you will need to reconnect the power supply cables.

5 Remove the old power supply. For instructions, see your

computer’s user guide.

6 Install the new power supply and secure it to the computer case

with the appropriate screws.

7 Reconnect all power supply cables using the notes you made in

step 4. Make sure that each connection is secure.

8 Close the computer case. 9 Plug the power cord into your computer, then turn your computer

on.

Troubleshooting

If your new power supply is not working correctly, try the following:

• Make sure that the computer power cord is firmly plugged into the power cord connector on your computer.

• If you are using a surge protector, make sure that it is plugged in and turned on.

• Make sure that the wall outlet is supplying power. For example, plug a lamp into the outlet and turn it on.

• Make sure that the red voltage switch (located on the back of the power supply) is set to the correct voltage setting. The setting for the United States is 115 V. The setting for Europe and other countries is 230 V.

• Make sure that the system board power supply cable is securely connected to the system board connector (24 pin or 20 pin).

• Make sure that all power supply cables to peripheral devices, such as hard drives, optical drives, and fans, are securely connected.
